If the first Thursday night of October was a boring one for you in L.A., you did it wrong. While LeBron James and the Los Angeles Lakers played at Staples Center, The Kills were opening for Interpol at the Hollywood Bowl. Across a similar expanse, Dumpstaphunk and Pigeons Playing Ping Pong went head-to-head from The Mint in Mid-City and the Teragram Ballroom near Downtown L.A.

And while nobody who attended any of those other events would’ve likely left disappointed, the most mesmerizing moments may well have been reserved for Lawrence‘s eye-opening performance at El Rey Theatre in Koreatown.

Nearly a month since they dropped their latest album, Living Room, the native brother-sister duo of Gracie and Clyde Lawrence returned to Southern California with more confidence and charisma in their sound than ever before.

Clyde, 24, brought his blend of “John Mayer Lite” vocals and shimmering soul-pop keyboards to bear throughout the set, featuring star turns from Living Room cuts like “The Heartburn Song” and “Probably Up” to “Friend or Enemy” and “Too Easy”. The ensemble of soaring horns, ripping guitars and pinpoint percussion behind the New York-bred siblings did its part to support the family dynamic, while taking turns stealing the spotlight—that is, however much of it was left once Gracie was done with it.

The 21-year-old actress-turned-singer stepped out like never before. Where once she seemed hesitant to overshadow her older brother, this time she seized the title of “lead vocalist”—along with the hearts and minds of the younger-skewing crowd of several hundred fans fawning from the floor. Between leading roles on “Limbo”, “Misty Morning”, “Shot”, and “Make a Move”, Gracie took her prodigious pipes for a walk, a jog, a run and a 100-meter dash, for good measure. Even her stints singing solidly alongside Clyde on longtime Lawrence staples like “Do You Wanna Do Nothing With Me?” and “Superficial” showed that, if there were any vocal sibling rivalry in that household, there looks to be a clear winner now.

That’s no disrespect to Clyde, let alone the rest of the band. They’re all terrifically talented, and would likely make for a fun and fresh act on their own. But Gracie, with her vast vocal graces, is the one who takes this act from solid to supersonic. She turned Sean Paul’s “Get Busy” into a funky frolic, and more than held her own on a rendition of the Carole King-, Gerry Goffin-, and Jerry Wexler-penned Aretha Franklin anthem “Natural Woman” to close out the show.

Lawrence doesn’t need Lady Gaga and Bradley Cooper to know that a star’s been born—they have one right in front of them and now firmly fronting them, perhaps to even greater measures by the next time they return to America’s Entertainment Capital.
